Actitis macularia (Linnaeus). Spotted Sandpiper. 
Common from early spring till about the middle of October, 
and perhaps a breeding species. Typical of zone four, as is the 
semipalmated species, from which zone it was not found to 
depart. 
Oxyechus vociferus (Linnaeus). Killdeer. 
Found onty within zone four; as there is practically no suit- 
able nesting ground within the formation, it is probably not a 
breeding species in the area. 
Order GALLINAE 
Colinus virginianus virginianus (Linnaeus). Bob-white. 
A common resident and breeding species. In winter a resi- 
dent of zones five and six; in summer of zone eight, as previously 
discussed. 
Bonasa umbellus umbellus (Linnaeus). Ruffed Grouse. 
Common in zones five and six during the winter, and in zone 
seven during the summer, in which association it breeds. 
Tympanuchus americanus americanus (Reichenbach). Prairie 
Chicken. 
Confined most strictly to zone eight, where it is not improb- 
able that the species nests. Very uncommon. 
Order COLUMBAE 
Zenaidura macroura carolinensis (Linnaeus). Mourning Dove. 
A few r pair of these birds nested in the outer border of zone 
seven, but the species is not nearly as common within the forma- 
tion as across the lake where conditions are more open, and a 
supply of grain food more abundant. 
Order RAPTORES 
Circus hudsonius (Linnaeus). Marsh Hawk. 
Abundant in and above zone five. The food consists largely 
of mice, principally Microtus pennsylvanicus , and often frogs, 
and on one occasion a female was seen flying away with a small 
specimen of snake, probably Thamnophis radix. Several pair 
breed within the confines of the swamp. 
Accipiter velox (Wilson). Sharp-shinned Hawk. 
Rather uncommon, fortunately. Two specimens were taken
